IMPROVEMENT IN CORN-PLANTERS.

The Schedule referred to in these Letters Patent and making part cf tne same.

To all whom t may concern.'

Be it known that I, DA'vID F. WAGNER, of 'West Hanover, in the county of Dauphin, and State of Pennsylvania, have invented certain new and useful Improvements in Corn-Planters; and I do hereby dcclare that the following is a full, clear, and exact description thereof', reference being had to the accompa-A nying drawings, making part of this specification', in which- Figure 1, plate 1, isa top view of the improved corn-planter.

Figure 2, plate 1, is a rear end elevation of the same.

Figure 3, plate 2, is a section, taken longitudinally 'through the planter, iu the vertical plane indicated by lilies X X in 1 and 2.

Figure 4, plate 2, is a longitudinal section, taken centrally through one of the seed-hoppcrs and dropping-devices.

Figure 5, plate 2, is a cross-.section through iig. 4, in the -plane indicated by line Z Z iu-ig. 3.

Figure 6, plate 2, is a top view of the interior ro- "tating cylinder, showing the two sets of peiforations. A Figure 7, plate2, is a perspective view of one of the seed-tubes, its rollers, and portions 'of its draw and stay-bars.

Similar letters of reference indicate corresponding parts in the several figures. n

This invention relates to certain improvements on corn-planters, wherein the hoppers' are caused to r0- tate, and at proper times discharge the grains through stationary cylindrical casings, inV which the hoppers rotate, and through tubes which are supported' upon the ground by means of rollers.

The nature of my invention consists- First, in connecting the frame of the machine to the axle of two transporting-wheels, by means of the cylindrical casings,in which the hoppers rotate, and in applying the rocking bar, from which the seed-tubes are Iliungby chains, `and by which these tubes can be raised or depressed, to goosenecks, which. are secured to' the ends of said frame, and which serve as its longitudinal braces, as will `be hereinafter explained.

Second; in connecting each one of theseed-tubes,

:which guide the seeds into the drills, to pendants,

which are secured to the front cross-beam ofthe frame by means of two pivoted bars, one of which is counected to its pendant by means of a wooden pin, and hooked on its end, so that should the seed-tube meet -with an obstruction in its path, which would 'be liable lo break or derange the machine, the wooden pin would break and allow the tube to fall back, 'and the said pivoted bar would drop ashort distance and be caught hy its hooked 'end falling upon a pin arranged below said wooden pin, as will be hereinafter' explained.

Third, in connecting the axles of each pair ot rollers Fourth, in having two sets of peiforations through l each hopper and its casing, in combination with an adjustable double perforated slide, whereby the corn can be dropped threegrains in a hill, or dropped in sixwle grains, at short distances apart, at the pleasure oft ie attendant, will be hereinafter explained.

Y To enable others skilled in the art to understand my invention, I will describeits construction and operation.

In the accompanying drawings- A represents a horizontal beam, which isarranged in front of and parallel with the axle C of two transporting-wheels,A2 A2.

To t iis beam four cylinders, B B B B, are rigidly secured, by means ot' bolts passed through flanges formed on these cylinders, and 4through the beam, which cylinders are arranged lat suitable distances apart for dropping in rows at regular distances apart.

lIn each one ofthe cylinders B, a cylinder-,19, is tted, to turn freely, which 'cylinder has closed ends, and is screwed rigidly to the axle C, which passes centrally through it, so that when. the machine is moved forward, one of the transporting-wheels, A2, which is fast ou said axle, will cause all the cylinders F to turn.

To the ends ofthe beam A, straps da are secured, which extend backward, and are curved over axle C," and provided with eye bearings on their rear ends, for supporting a horizontal rocking bar, I), having -hooks e iixed to it, from which the seed-tubes R are hung, by means of chains T, as shown in figs. 2 and 3.

The hand-lever d, which rises from bar D, enables a person sitting upon the seat S to raise or depress the vseed-tubes.

The seat S, on vwhich the person is located who inanages the machine, is arranged over or a little in rear of the axle C, and is mounted upona spring standard, Sl, which is secured, at its `front end, to the beam A, between the flanges of the'two intermediate cylinders, B B.

-The front ends of the straps da are extendedl forward of the beam A, and secured to the ends of a front beam, A1, so as to serve, in con] uuctionwith a central connection, c, as a means for sustaining said front beam rigidly in place,I so that it will constitute part of the frame of the machine.

To the front beam .A1-.the draught-pole Au is secured, and to this beam vertica1ly-slotted and horizontally-perforated pendants 7i, are also secured, at regular distances apart. v

To each one of .the pendants h a seed-tube, It, is connected, 4by a draw-rod, J, which is pivoted to its pendant, at fi, by a wooden pin, and which has a hook, j, formed on its front end, as shown in iig.3. f Below the wooden pin connection i a pin, t, is passed through the pendant 71., for the' purpose of catching the hooked end of the rod j when pin t' breaks, and

lthus prevent-ing this rod from dropping upon the ground.

The wooden pin connection 'i is designedto break should an obstruction be met with in the path of a seed-tube, which would be liable to break such tube.

The rod J is pivoted, at its lower rear end, 4to a short axle, V', that is passed transversely through the lower end of a ange, y', which is formed on the front side of each seed-tube R, as shown in figs. 2 and 7.

`Tubular eyes V are formed on the rear end of each d rawrod J, to receive the axle V', and on the ends of this axle V wheels s s are applied, an'd held in place by means of nuts and washers.

The wheels s s, which are applied to each seed-tube, support it upon the ground, and serve to lightly cover the grains with earth.

The rds or links g, which are pivotedy at 'their rear ends to the upper ends of the 'seed-tube iianges g', and at their front ends to staples fixed vto the rear side of the front beam A1, serve to connect the upper ends of the tubes to said beam, and allow the tubes to rise and descend vertically.

r.lhe grains of corn falling from the dropping-cylinders, are guided into the tubes R by the ilexible tubes T, which are secured by short rods u to the beam A, as shown in g.

I `will nwvrefer more particularly to the devices for dropping the grains of corn,'either three grains at a time, or one grain at a time.

The seed-hoppers F are rotating cylinders, turning within the stationary cylinders or cases B.

Openings 'n are made through the upper sides and near the inner ends ofthe stationary cylinders B, and also through cylindrical hoppers, for the purpose of introducing corn int-o the latter, which `can be done when the feed-openings through cylinders E, register with the corresponding openings through the cy1in' ders B.

Each stationary' cylinder B has a groove made longitudinally into its bottom for receiving a slide, E, through which holes are made, to allow the discharge of the grains of corn through it. Y

vThis slide passes through the bottoms of all the cylinders B, and is moved in a direction with its length by means of a 'laterally-vibrating foot-lever,- b, which is pivoted to theV top of beam A, in reach of a person sitting onl the seat S.,

The rear depressed end of the lever b is connected to the slide E by an adjnstablepivot, j, as will be further explained.

vthrough cylinder B at every revolution of the cylinder F, as shown in iig. 4.

lVh'en the slide E is adjusted so that the holes through it, through which the lcorn drops, are in the plane of the holes ll Z, as shown in tig. 4, the corn will :be dropped three grains in a hill, and when the slide' E is adjusted so that the holes through it are in the plane of' holes m1 on", the coru'will be discharged from each hopper, one grain ata time.

When it is desired to adjust the slide for dropping from holes m1 lm", the pivot-pin f is removed and inserted through hole m2, so that 'the lever b can be moved for cutting off the discharge from hole'sm1 m", when it is not desired' to plant.

Having described my invention,

lVh'at I claim as new, and desire to secure by Lettels Patent, is

l. The frame A A1 a, connected tothe axle of two transporting-whcels, by means of the casings B, in which turn the h'oppers F, substantially as described. 2. The bar D, from which the seed-tubes are hung, applied to the rear overhanging ends of straps a a., when these straps also serve to connect together the two beams, A A1, and when these two beams are sustained by the cylindrical hopper casings B, substantially as described.

3. The plvoted draw-rods j, hooked on their front ends and pivoted to the pendants h, by means of Wooden pins ,in combination with the catch-pins t, arranged below, pins fi, substantially as described.

4. The double perforated 'rotating hopper F, applied upon axle C. and combined with a stationary case, B,

and an adjustable slide, E, all constructed substantially as described.

5. The tubular eyes V, on the rear end of draw-rod J, applied to the axle V of wheels s s and to ila-nge y of tube E, substantially as described.
